v
   
Regularly
 
inspect
 
and
 
maintain
 
your
 
electrical
 
hand
 
tools
 
for
 
safe
 
operational
 
condition.
 
v
   
Do
 
not
 
use
 
worn
 
or
 
broken
 
tools
 
and
 
testers.
 
v
   
Never
 
assume
 
that
 
power
 
has
 
been
 
disconnected
 
from
 
a
 
circuit.
 
First,
 
check
 
that
 
it
 
has
 
been
 
powered-off.
 
v
   
Always
 
look
 
carefully
 
for
 
possible
 
hazards
 
in
 
your
 
work
 
area.
 
Examples
 
of
 
these
 
hazards
 
are
 
moist
 
floors,
 
nongrounded
 
power
 
extension
 
cables,
 
power
 
surges,
 
and
 
missing
 
safety
 
grounds.
 
v
   
Do
 
not
 
touch
 
live
 
electrical
 
circuits
 
with
 
the
 
reflective
 
surface
 
of
 
a
 
plastic
 
dental
 
mirror.
 
The
 
surface
 
is
 
conductive;
 
such
 
touching
 
can
 
cause
 
personal
 
injury
 
and
 
machine
 
damage.
 
v
   
Do
 
not
 
service
 
the
 
following
 
parts
 
with
 
the
 
power
 
on
 
when
 
they
 
are
 
removed
 
from
 
their
 
normal
 
operating
 
places
 
in
 
a
 
machine:
 
   
Power
 
supply
 
units
 
   
Pumps
 
   
Blowers
 
and
 
fans
 
   
Motor
 
generators
 
and
 
similar
 
units.
 
(This
 
practice
 
ensures
 
correct
 
grounding
 
of
 
the
 
units.)
 
v
   
If
 
an
 
electrical
 
accident
 
occurs:
 
   
Use
 
caution;
 
do
 
not
 
become
 
a
 
victim
 
yourself.
 
   
Switch
 
off
 
power.
 
   
Send
 
another
 
person
 
to
 
get
 
medical
 
aid.
Safety
 
inspection
 
guide
 
The
 
intent
 
of
 
this
 
inspection
 
guide
 
is
 
to
 
assist
 
you
 
in
 
identifying
 
potentially
 
unsafe
 
conditions
 
on
 
these
 
products.
 
Each
 
machine,
 
as
 
it
 
was
 
designed
 
and
 
built,
 
had
 
required
 
safety
 
items
 
installed
 
to
 
protect
 
users
 
and
 
service
 
personnel
 
from
 
injury.
 
This
 
guide
 
addresses
 
only
 
those
 
items.
 
However,
 
good
 
judgment
 
should
 
be
 
used
 
to
 
identify
 
potential
 
safety
 
hazards
 
due
 
to
 
attachment
 
of
 
non-IBM
 
features
 
or
 
options
 
not
 
covered
 
by
 
this
 
inspection
 
guide.
 
If
 
any
 
unsafe
 
conditions
 
are
 
present,
 
you
 
must
 
determine
 
how
 
serious
 
the
 
apparent
 
hazard
 
could
 
be
 
and
 
whether
 
you
 
can
 
continue
 
without
 
first
 
correcting
 
the
 
problem.
 
Consider
 
these
 
conditions
 
and
 
the
 
safety
 
hazards
 
they
 
present:
 
v
   
Electrical
 
hazards,
 
especially
 
primary
 
power
 
(primary
 
voltage
 
on
 
the
 
frame
 
can
 
cause
 
serious
 
or
 
fatal
 
electrical
 
shock).
 
v
   
Explosive
 
hazards,
 
such
 
as
 
a
 
damaged
 
CRT
 
face
 
or
 
bulging
 
capacitor
 
v
   
Mechanical
 
hazards,
 
such
 
as
 
loose
 
or
 
missing
 
hardware
 
The
 
guide
 
consists
 
of
 
a
 
series
 
of
 
steps
 
presented
 
in
 
a
 
checklist.
 
Begin
 
the
 
checks
 
with
 
the
 
power
 
off,
 
and
 
the
 
power
 
cord
 
disconnected.
 
Checklist:
 
1.
   
Check
 
exterior
 
covers
 
for
 
damage
 
(loose,
 
broken,
 
or
 
sharp
 
edges).
 
2.
   
Power-off
 
the
 
computer.
 
Disconnect
 
the
 
power
 
cord.
 
3.
   
Check
 
the
 
power
 
cord
 
for:
   
Chapter
 
10.
